NAME

personality - set the process execution domain

SYNOPSIS

#include<sys/personality.h>intpersonality(unsignedlongpersona);

DESCRIPTION

Linux supports different execution domains, or personalities, for each
process. Among other things, execution domains tell Linux how to map
signal numbers into signal actions. The execution domain system allows
Linux to provide limited support for binaries compiled under other
Unix-like operating systems.
This function will return the current personality() when persona equals
0xffffffff. Otherwise, it will make the execution domain referenced by
persona the new execution domain of the current process.

RETURNVALUE

On success, the previous persona is returned. On error, -1 is returned,
and errno is set appropriately.

ERRORS

EINVAL The kernel was unable to change the personality.

CONFORMINGTO

personality() is Linux-specific and should not be used in programs
intended to be portable.
